Abstract: ABSTRACT    Apparatus for delivering singularized stacks of paper sheets to a packing machine has a first conveyor which intermittently receives groups of several abutting stacks and is intermittently driven by a variable-speed electric motor to advance the groups onto the individual endless bands of a gathering conveyor which serves to accumulate the groups into a row of abutting stacks ready to be singularized and delivered to the packing machine.          The bands of the gathering conveyor are normally driven at a constant speed by a prime mover which further drives a first encoder serving to transmit a first signal whenever the bands cover a unit distance.  A second encoder generates second signals whenever the motor is on and the first conveyor covers the same unit distance.  The motor can also drive the bands at a speed higher than that at which the bands can be driven by the prime mover whenever the speed of the first conveyor exceeds the speed of the bands.  The first and second signals are compared in a stage which controls the speed of the motor and can turn the motor off during the intervals of stoppage of the first conveyor, either for the purpose of receiving a fresh group of stacks or for the purpose of segregating one or more stacks from those which are destined for delivery to the first conveyor.  During stoppage of the first conveyor for the purpose of receiving a fresh group, the first signals are transmitted to a first counter which then causes the stage to influence the motor so as to drive the first conveyor at a higher than normal speed as soon as the delivery of a group is completed.  If the first conveyor is arrested during segregation of one or more stacks, the first signals are stored in a second counter which thereupon influences the stage to establish in the series of singularized stacks gaps at appropriate intervals enabling the packing machine to perform idle cycles.

Abstract: A B S T R A C T   The method by which a token-passing local-area network having from two to 2n modules is initialized, where n is an interger greater  than  zero.   When  connected  into  the  network  and energized, each module determines if the network is initialized and, if not, which module is to do so.  Each module has a unique n  bit  network  address.  The module with the smallest network address energized before the network is initialized is identified and begins the process of initialization by transmitting tokens addressed sequentially to network addresses beginning with the next higher address than its own until a token so transmitted is accepted  by  an  addressed  module  or  until  a  token  has  been addressed  to  all  network  addresses  other  than  that  of  the initiating  module.  If  after  tokens  are  transmitted to  all possible  network  addresses  other  than  that  of  the  initiating module,   the   initiating  module  generates  a  fault  signal  to indicate its status.

Abstract: ELECTROMAGNETIC ACTUATOR USING STEPPER MOTOR          WITH CLOSED LOOP POSITION SENSING, ELECTRONIC COMMUTATION AND DYNAMIC          POSITION AND ANOMALY CORRECTION                ABSTRACT OF THE DISCLOSURE            Using as an actuator a stepper motor operated in a position-sensed closed loop mode via an electronic commutator by position and anom-aly corrected motion control signals provided by a programmable logic array and by a microprocessor, provides a precision power positioner.          The correct enabling of the motor coils, based on position sensing of the motor phase, using electronic commutation for the stepper motor, transforms the problem of enabling coil selection to the programmable logic array, which by its logic provides a simplified operating control as a function of present armature position feedback, and by a micro-processor corrects for anomalies such as temperature rise, square-law, and phase increase as a function of position desired and present arma-ture position feedback signals, and thus provides high positional accu-racy, high speed and force (torque) control independent of the motor cardinal step positions. A standard three phase magnetic resistor sen-sor is used both to sense the motor phase and to feed back the motor position to the microprocessor for calculation of corrections; actual control of the stepper motor is communicated as a single amplitude modulated control signal.

Abstract: ABSTRACT      Disclosed is a nondestructive optical method for detecting defects (e.g., open regions) in thin opaque or non-opaque films formed on a ceramic substrate by utilizing the inherent fluoresceability of the ceramic material.  The film-clad ceramic is illumined with an intense optical radiation consisting of at least one wavelength which corresponds to the excitation band(s) of the ceramic component responsible for fluorescence.          In case of an opaque film, the incident light will reach the ceramic in regions corresponding to the defects causing these ceramic regions to fluoresce at a different wavelength than that of the incident light.          The fluorescent radiation emanating from the ceramic will provide a high contrast optical image of the defects particularly when viewed through a filter which transmits only the fluorescent radiation.  In case the film is non-opaque, the incident light will generate fluorescent radiation over the entire substrate - both the defective and non-defective regions.  However, the intensity of the fluorescent light emanating from the defective regions will be higher than that from the non-defective regions due to absence of any absorption of the incident and fluorescent light by the defective regions of the film.  By analyzing the intensity of the fluorescent light emanating from the entire film-clad substrate, defects in the non-opaque film can be ascertained.

Abstract: LOCAL AREA NETWORK Abstract A modular, hierarchical local area network is realizable by using existing twisted pair wiring, for example, in a building together with several elements known as network access units and hub units.  A network access unit is connected to a device (microprocessor, display terminal, peripheral device, other local area network, information systems network or the like) in the local area network to give that device access to and from the network.  The network access device is designed for simple daisy chaining with other devices to form a node when devices are colocated in the same section or room in the building.  The hub unit is the network building block which permits extensive expansion of the local area network.  It provides a connection point for access units or other hub units, performs collision detection operations, if necessary, and serves as a loop-back point for the network.          Switchably connectable termination impedances and loop-backs are automatically passed to the appropriate points in the local area network.           While most small local area networks are considered for intra-building applications, the present network is applicable to inter-building applications, also.
